The measurement or constraint of the masses of neutron stars and their binary companions tests theories of neutron star structure and of pulsar formation and evolution. We have measured the rate of the general relativistic advance of the longitude of periastron for the pulsar PSR B1802−07: ω̇ = 0. 060 ± 0. 009 yr, which implies a total system mass, pulsar plus companion star, of M = 1.7 ± 0.4M⊙....

We used mitochondrial DNA and microsatellite loci to examine the phylogeographic patterns of the most broadly distributed lizard in eastern North America, the five-lined skink (Eumeces fasciatus). We infer that longitudinal phylogeographic patterns in E. fasciatus are consistent with fragmentation due to refugial and post-glacial dynamics, but that deep divergences within the species imply hist...

Urbanization is one of the major forms of habitat alteration occurring at the present time. Although this is typically deleterious to biodiversity, some species flourish within these human-modified landscapes, potentially leading to negative and/or positive interactions between people and wildlife. Hence, up-to-date assessment of urban wildlife populations is important for developing appropriat...

The products of the shc gene appear to be substrates for activated oncogenic tyrosine kinases, such as v-Src and v-Fps and activated tyrosine kinase receptors like the epidermal growth factor (EGF) and platelet-derived growth factor (PDGF) receptors. We investigated whether the Shc proteins are targets for the activated insulin receptor tyrosine kinase. Here we show that the 46- and 52-kDa Shc ...

Interactions between hosts and associated microbial communities can fundamentally shape the development and ecology of 'holobionts', from humans to marine habitat-forming organisms such as seaweeds. In marine systems, planktonic microbial community structure is mainly driven by geography and related environmental factors, but the large-scale drivers of host-associated microbial communities are ...
